AUTOMATIC RAI LWAY SWlTCH,

SPECIFICATION forming part of Letters Patent No. 336,058, dated February9,1886.

Application filed June 8, 1885. Serial No. 168,000, (No model.)

To all whom it may concern.-

Be it known that we, IVANHO W. NEWLAND, WILLIAM J. IREDALE, and ALONZOH. Nnw- LAND, all of Boulder, in the county of Boulder, and State ofColorado, have invented a certain new and useful Improvement inAutomatic Railway-Switches, of which the following is a full, clear, andexact description, reference being had to the accompanying draw- 10ings, forming part of this specification, and in which-- Figure 1 is atop view of our improved switch, showing also the end of a car with thetrip for working the switch. Fig. 2 is a side view of same with the tripdown out of position for striking the switch-levers. Fig. 8 is anenlarged transverse section taken on line 3 3, Fig. 1.

Our invention relates to railway-switches, by means of which anengineer, brakeman, or

trainman can operate the same without leaving his engine, car, or train;and the objects of our improvements are, first, to avoid danger to lifeand limb of railroad employs in 2 5 switching trains, by avoiding thenecessity of their having to leave a train in order to switch it;secondly, to avoid delays and stoppages of trains while switching;thirdly, to avoid smaslr ups or damages occasioned by misplaced or openswitches, as our switch cannot be operated or left so as to wreck atrain; fourth, to insure greater safety to the traveling public, and theleast amount of damage to shippers and railroad-owners, by enabling anengineer of atrain in running forward or a conductor or brakeman inbacking to make a switch, and various other reasons that need not bementioned.

Our invention consists in features of novelty 4o hereinafter fullydescribed, and pointed out in the claims.

Referring to the drawings, A represents the switch, and B switch-lockspivoted at B to an iron hearing or support.

0 represents the main rails.

D are iron arms or levers pivoted at D at or near the inner ends of thelevers, and to these arms are attached ropes or chains Iby means of anadjustable swivel, J. These ropes or chains-- or rods may be used--passaround sprocket wheels or pulleys L on rock-shafts M, journaled in boxesN, secured to suitable supports. On the outer ends of the shafts aresecured levers O, bifurcated or forked at top, as shown, and

being of the proper height for a trip, P, on the ear to come against thefaces T of the forks, which are preferably roughened to prevent slippingof the trip thereon.

U represents the switch-stand, and V the target or hand-switch. The tripcan be thrown 6 0 into the position shown in Fig. 1, to operate theswitch, or into the position shown in Fig.

2, to miss the levers and not operate the switch, by any suitable means.\Ve have shown it provided with a handle, P, for that purpose. 6

When the levers are moved by the trip coming against one of their arms,as stated, they turn their shafts, which move the rope, rod, or chain,and operate the locks, forcing the switch in either direction, accordingto which lever is struck by the trip. A moving train can thus throw theswitches for itself or for a coming train, or for both itself andanother train, or can pass by throwing the trip down without operatingthe switch at all.

The roughened surface of the forks of the lever may be made of rubber toform bumpers.

Ve claim as our invention 1. The combination, with the switch-rails, ofa pair of alternately-engaging switch-locks, a rope or chain connectedto each of said locks, and a pair of rock -shafts with which said ropesor chains engage, whereby the parts connected to the respective locksare moved in opposite directions, as set forth.

2. The combination, with the alternatelyengaging switch-locks B B, of anendless rope or chain, I, to which said locks are connected, as shownand described, a rook-shaft with which said endless rope or chainengages, and a lever for rocking said shaft.

3. The combination oftheswitch,locks,rockshafts, connection betweenthelocks and shafts, bifurcated levers, trip, and rubber bumpers on thearms of the lovers, substantially as set forth,

4. The combination of the switcli,locks,rockor chains pass,. levers onthe shafts, and trip, 10 shafts, sprocket wheels or pulleys on theshafts, substantially as set forth. connection between the pulleys andthe locks,
